The November 5th copy of the New York Times sold out in a second, and is now going for ridiculous prices on eBay (it was up to $1000 at one point, but seems to be settling down now).
So how to get your hands on a copy, guaranteed? It's no puzzle:

Actually, it is a puzzle. Hammacher Schlemmer will make a 400 piece jigsaw puzzle out of any NY Times cover... Including Nov. 5th's historic Obama headliner.
